As a brand-new high-tech product, the recording shielder has gradually entered people's field of vision. It can prevent illegal recording and protect the privacy and safety of your conversations in many occasions! The principle is: the recording shield sends out a The interference signal makes the pickup (microphone) of the sound acquisition device fail, so that it can only pick up the interference signal, but not the normal voice signal, thus achieving the purpose of voice shielding. After the jammer is turned on, the files recorded by the recording equipment are played with a "humming" sound and the content of the conversation at that time cannot be heard. This product is widely used in confidential meetings, high-end business talks, military meetings and other places to prevent illegal recording. There are many types and forms of recording shielding products on the market. How to choose a good recording shielding product has become a problem that needs to be solved.
So, what constitutes a useful and practical anti recording blocker product? According to the author's many years of investigation, a qualified product should follow the following points:
1. Kit dènye modèl ekipman anrejistreman an ka pwoteje se premye kesyon yo dwe konsidere. Pou egzanp, dènye modèl iphone, iphoneX/XR/XS/max, elatriye Kòm nou tout konnen, ekipman anrejistreman aktyèl la te fèt ak rediksyon bri ak filtraj nan tou de lojisyèl ak pyès ki nan konpitè, ki mande pou plak pwotèj anrejistreman an teknikman entegre. dènye ekipman anrejistreman sa yo. Li kapab tou byen pwoteje yo dwe konsidere kòm yon pwodwi ki kalifye, ki ta dwe remake lè w ap chwazi yon pwodwi.
2. Whether the audio recording jammer will cause discomfort to the human body after it is turned on is a very important issue. The recording shielding device realizes shielding by emitting shielding signals. The frequency and algorithm used by different manufacturers of the shielding signal are very different. The frequency and algorithm determine people's feelings and shielding effect. According to the author's investigation, after many products start working There will be sharp or harsh sounds, which will make people feel uncomfortable. Such products should be avoided as much as possible.
3. Èske li ka pwoteje nan tout ang? Anpil jammers sou mache a gen yon dezavantaj evidan, se sa ki, efè a pwoteksyon ka sèlman reyalize lè jammer anrejistreman an ap fè fas a pickup nan aparèy anrejistreman an (tankou yon telefòn mobil, achiv vwa, elatriye), yon fwa pickup la ak jammer anrejistreman an fòme yon ang. Ak piti piti ogmante, efè a pwoteksyon pral piti piti febli. Lè li rive nan 180 degre, pifò plak pwotèj anrejistreman pa gen okenn efè pwoteksyon. Sa a se yon pwoblèm relativman detaye ak relativman pwofesyonèl. Li difisil pou moun ki pa gen eksperyans konprann li. Nou itilize dyagram sa a pou ilistre:
As long as you keep the above three points in mind, and then choose a Audio jammer /noise generator that suits your usage habits according to your own situation, especially the characteristics of easy portability and flexible placement, for example, it can be placed in the car, on the desk, or Conference table, etc., you can refer to AL ASAR TECH's recording jammer products. Their products have the inspection report of the Ministry of Public Security and are regular manufacturers. You can pay attention to it, I believe that some people who have the need for conversation confidentiality should really choose a convenient, easy-to-use and practical recording shield to protect your conversation privacy.
